WebSphere 6 and ActiveMQ 4.0.1

Hi,

we are deploying our application on WebSphere 6. Our application contains
ActiveMQ 4.0.1 resource adapter in the ear file. We start the broker as
embedded and our consumers are Message Driven Beans. Our Publishers are
Session Beans.

We publish ObjectMessages to our Queue's. When we publish messages there is
no problems. Nevertheless, when the MDB's are called to consume a message
the following exception arises:

nexpected (non-declared) exception during invocation of method "onMessage"
on be
an "BeanId(SysTAO#TherapeuticProgramEJB.jar#ControlValidatedMessage, null)".

Did someone get this ClassCastException before? Any tip?

Thanks,

Re: WebSphere 6 and ActiveMQ 4.0.1

It looks like you have a classloader issue.  Perhaps ActiveMQObjectMessage
is being loaded at multiple places in your classloader tree?
